This allows returning WOULD_BLOCK without allocating a GError, and
should later be used for various functions of GPollableOutputStream,
GPollableInputStream and anything else that can potentially block.
Interpret the value "help" for environment variables that
are passed to _g_io_module_get_default(), and print the
names and priorities of available extensions.
This lets users explore what is available, and can be helpful
in figuring out why a certain extension was chosen as default.
It is similar in spirit to what we already do with environment
variables like G_DEBUG.
They’re out of date. Probably best to leave the document unsigned, since
it’s supposed to be endorsed by all the GLib maintainers.

This is useful for debugging in many situations. It’ll be printed with
G_MESSAGES_DEBUG=GLib-GIO or G_MESSAGES_DEBUG=all.
Mostly I need it for debugging the default GNetworkMonitor, but it will
work for all GIO module implementations.

When we are in a sandboxed situation, bump the priority
of the keyfile settings backend above the dconf one,
so we use a keyfile inside the sandbox instead of requiring
holes in the sandbox for dconf.
Stacked databases and locks are dconf features that allow
management software like Fleet Commander to set system-wide
defaults and overrides centrally for applications.
This patch adds minimal support for the same to the keyfile
backend. We look for a keyfile named 'defaults' and a
lock-list named 'locks'.
Suitable files can be produced from a dconf database with
dconf dump and dconf list-locks, respectively.
The default location for these files is /etc/glib-2.0/settings/.
For test purposes, this can be overwritten with the
GSETTINGS_DEFAULTS_DIR environment variable.
Writes always go to the per-user keyfile.
Make it possible to instantiate a keyfile settings backend
without specifying parameters, by turning the arguments to
the new() function into construct-only properties. If no
filename is specified, default to
$XDG_CONFIG_HOME/glib-2.0/settings/keyfile
Rather than prefixing unsigned numbers with unary minus operators and
expecting the implicit cast to carry the correct value through, add an
explicit cast to a signed type before the unary minus is applied.
In all four cases, an overflow check has already been done.

It needs investigating and fixing properly, but let’s not let it disrupt
the CI in the meantime.

Rather than storing it as an invalid value in last_position, store it as
a separate boolean.
This introduces no functional changes, but should fix some warnings from
MSVC.

The subprocess needs to access the test_log_fd. If the file descriptors
are not left open, functions such as g_test_message may stomp on file
descriptors open by the subprocess and cause bad behavior of the test.
(Tweaked by Philip Withnall <bugzilla@tecnocode.co.uk> to fix review
comments.)
